Hi, I'm hoping someone can give me advice on this problem with my alarm system. Castle Integrated Security (Kirkliston) installed a home security system as a sub-contractor to Wimpey in my home in 2007. The system was linked to the police for the first couple of years then I stopped the contract. The system proceeded to work as normal for the 2018 when I noticed regular significant telephone charges on my BT phone bill which when I checked all were calls to the same premium number. These were calls to a number 08716648336 which I did not recognise but which when checked online appears to be to a number which is used by security companies to test security systems but I don't understand why that would be the case as I hadn't been under contract since 2009? As far as I understand Castle Integrated Systems were sold shortly after installing my system and I can't think how they could have changed the testing frequency which hadn't been causing the volume of calls which I discovered in 2018 literally many dozens of repeat calls with seconds of each other amounting to hundreds of £sss! The only way I could think of stopping the calls and expense was by disconnecting the telephone line from my security system box. This has indeed stopped these excessive calls and costs but of course my alarm system no longer works as it senses a communication problem and won't set. When I connect the telephone line again the system works fine. I'd appreciate if anyone can advise if and how I can get round this problem. Thanks Cheers Bill
